Description

Detailed Description of the Invention [Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable carrier capable of easily carrying small parcels, and more particularly to a carrier having a handle member provided with a fixing member for preventing distortion of the handle part and having the handle part extendable. It is a thing.

[Prior art]

[0002] In the handle portion of a conventional carrier, a plurality of pipes are inserted so as to be expandable and contractible in accordance with the size of the caliber.
Engagements that prevent the pipes from coming off are engaged with the small holes provided at the connecting ends of the pipes when they are extended. In addition, at the time of contraction, the operating rod for releasing is slid along the pipe, and the contact between the inclined surface provided on the operating rod and the engaging member causes the engaging member to retract in the releasing direction, so that the contracting is possible. ing.

Prior arts of this type include, for example, Japanese Patent Laid-Open No. 52-59437 (a telescopic assembly for a portable baggage carrier) and Hei 2-224 (carriage). The pair of pipes has a pair, and the upper pipe has a handle, and the lower pipe is provided with a load carrying table pivotally attached to the lower pipe by a shaft so that one or two slidable release rods are provided between the pair of pipes. Not only is this provided and the engagement element is released, but it also serves as some support so as to prevent unstable wobbling due to distortion of the handle portion during transportation.

[0004]

Unstable wobbling during transportation is caused by a handle between a pair of first pipes which are directly fixed to the handle, such as in the case of No. 2-224 (transport vehicle). This is because there is no fixing member for preventing the distortion of the part. In other words, even if the releasing member is present in the grip portion, since this releasing member is fitted with play so that it can be moved up and down along the pipe, the distortion of the handle portion is positively eliminated. I can't.

Further, in the handle portion as in the above-mentioned Japanese Patent Laid-Open No. 52-59437 (a nesting type assembly for a portable baggage carrier), a pair of pipes are arranged in three lines and an engaging member is provided on each pipe. Since the first release member that connects the second pipe and the third pipe and removes the engaging element and the second release member that removes the engaging element that connects the first pipe and the second pipe are present, the grip portion Since it is not possible to positively eliminate the distortion, it is necessary to interpose and fix a fixing member for preventing the distortion of the handle portion between the pair of first pipes. Then, since it is necessary to provide the above-mentioned three members for each of the first pipe to the third pipe, not only the carrier feels heavy in appearance, but also a small-sized transport can be performed even if the handle portion is expanded and contracted and folded. It has the drawback that it lacks aesthetic appeal as a car, and therefore its appearance as a product image is greatly inferior.

In order to eliminate such drawbacks, it is an object of the present invention to prevent the handle portion of the carrier from wobbling and to expand and contract the handle portion of the carrier during the movement of the carrier carrying the load.
Furthermore, it is to improve the appearance even when the receiving tray is folded.

[Means for Solving the Problems]

In order to achieve such an object, the present invention has a handle held by hand, a pair of first pipes having one end fixed to the handle, and a first fixing member for supporting the pair of first pipes. The third pipe is provided between the positions where the second pipe and the third pipe are connected.
A second fixing member for supporting the pipe, a bracket fixed to the lower portion of the third pipe, wheels provided at both ends of a wheel shaft penetrating the bracket, and a load receiving base having both ends fixed to the pivot of the bracket. , The pair of first pipes are slidably fitted into the second pipe, and the first small hole is formed in the lower part of the first pipe and the second small hole is formed in the upper part of the second pipe. A first engaging element that moves forward and backward and is urged by a spring member, a third small hole formed in a lower portion of the second pipe, and a fourth small hole formed in an upper portion of the third pipe, and A second engaging member urged by a spring member, and the first fixing member is a concave opening on the lower surface side.

A second fixing member is formed on the upper surface of the second fixing member, an inclined surface for engaging the first engaging element is formed at both lower ends, and an inclined surface is engaged with the second engaging element at both upper ends. A slidable releasing member that forms a mating inclined surface and a spring member that urges the releasing member are internally provided, and the reduction of the handle portion is
When the release member is pushed down against the spring member, the inclined surface below the release member causes the second engaging element to move from the third small hole to the fourth small hole.
At the same time as it is retracted in the direction of the small hole, the handle can be pushed down, the second pipe slides into the third pipe, and the next first engaging element abuts the inclined surface above the release member,
When the first pipe is moved back and forth in the direction of the second small hole and the first pipe is slid into the second pipe, the upper part of the release member is the first.
It is to be buried in the recess of the fixing member.

[Action]

When the release member is pushed down against the spring, the inclined surface of the release member causes the second engaging element to retreat from the third small hole toward the fourth small hole, and at the same time allows the handle to be pressed down. ,
The second pipe is slid into the third pipe, and while the next first engaging element is in contact with the inclined surface of the second fixing member, the second pipe is advanced and retracted in the direction from the first small hole to the second small hole to move the first pipe. When it is slid into the second pipe, the upper portion of the release member is embedded in the recess of the first fixing member.

1 and a load receiving base 50 having both ends 51 fixed thereto.

As described above, since the handle portions N and N'have the same structure and are a pair, only one handle portion N will be described in detail in FIG. The first pipe 1N is sized so as to be slidably fitted into the second pipe 2N. The first engagement element 3 urged by the spring member s is different from the first small hole 1h formed in the lower portion of the first pipe 1N and the second small hole 2h formed in the upper portion of the second pipe second pipe 2N. I try to move back and forth. The second engaging element 5 biased by the spring member s ′ can move forward and backward with respect to the third small hole 3h formed in the lower portion of the second pipe 2N and the fourth small hole 4h formed in the upper portion of the third pipe 3N. I am trying.

Further, the first fixing member 10 has a recess 12 having an opening on the lower surface side, and a slidable releasing member 60.
The upper surface of the second fixing member 20 faces the upper side, the inclined surfaces 61 engaging with the first engaging elements 3 are formed at both lower ends, and the inclined surfaces 61 engaging with the second engaging elements 5 are provided at both upper ends. The surface 62 is formed. The spring member 60s is provided below the release member 60 to urge it.

Therefore, the contraction of the grip portions N and N'is achieved by pressing the release member 60 against the spring member 60s by the inclined surface 61 of the release member 60.
Is retracted from the third small hole 3h toward the fourth small hole 4h, and at the same time, the handle 1 can be pushed down, the second pipe 2N is slid into the third pipe 3N, and the next first engaging element 3 While contacting the inclined surface 62 of the release member 60, the first small hole 1

Is slid into the second pipe 2N, the upper portion 60a of the release member 60 is embedded in the recess 12 of the first fixing member 10. Further, when the handle 1 is pulled upward, the respective engagement elements 3 and 5 are automatically engaged with the first small hole 1h to the fourth small hole 4h by the spring members s and s ', and the handle portion is expanded N and N'. Can be fixed.

As described above, the present invention includes the first fixing member,
The second fixing members are arranged above and below the handle, and the releasing member is pushed down against the spring member so that the inclined surfaces of the releasing member retract the first engaging element and the second engaging element respectively. At the same time, since the handle can be pushed down and the upper part of the release member can be buried in the recess of the first fixing member, not only does the appearance of the handle become smaller when it is reduced, but also the handle is distorted. Since this can be prevented and the carrier can be used in a stable state, the practical effect is sufficiently exhibited.
